Abstract: A lightweight, compact hyperspectral imaging system includes a fore-optics module and a wavelength-dispersing module. The imaging system may also include a detector, supporting electronics and a battery module. The fore-optics module may include a telescope with three or more mirrors, where the mirrors include a silver coating that provides high reflectivity over wavelengths in the visible and shortwave infrared portions of the spectrum. The modules of the imaging system may be incorporated in a housing having a longest linear dimension of 16 inches or less. The housing may be cylindrical in shape and have a length of 14 inches or less inches and a diameter of 8 inches or less.
